Building MPIR and GMPY using the Windows SDK tools



It is possible to build MPIR and GMPY from source on a Microsoft Windows

platform using the command-line compiler that is included with the Microsoft

Platform SDK. I've documented the process for a 64-bit build. The operating

system was Windows XP x64. The process isn't difficult but assumes some

familiarity with the command line.



1)  You should have an program for processing .zip and .tar.gz archives.



2)  Python should be installed on your system and the installation

    directory should be added to your system's PATH environment variable.



3)  Install .NET Framework 2.0 or later. (This is required for the

    installer used by the SDK.)



4)  Install the Microsoft Windows SDK. I used "Microsoft Windows SDK for

    Windows 7 and .NET Framework 3.5 Service Pack 1". It can be found at

    "http://msdn.microsoft.com/en-us/windowsserver/bb980924.aspx". Use the

    version appropriate for your system: X86 for a 32-bit system or AMD64

    for a 64-bit system.



5)  Download the current version of the YASM assembler. It can be found at

    "http://www.tortall.net/projects/yasm/". Again, use the version approp-

    riate for your system.



    The executable must be renamed to "yasm.exe" and copied to the SDK

    installation directory, typically:



    C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin



6)  Create a directory to use for the build process. I used C:\src.



    mkdir c:\src



7)  Download the GMPY and MPIR source code. This example uses

    gmpy-1.12.zip and mpir-2.1.1.tar.gz. They should be unzipped

    (or untarred) into c:\src. There should be c:\src\gmpy-1.12

    and c:\src\mpir-2.1.1 directories in c:\src.



8)  The file "yasm.rules" must be copied from



    c:\src\mpir-2.1.1\build.vc9\



    to



    C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\VCProjectDefaults



9)  Open a command window and enter the following commands:



    rem Configure the environment for 64-bit builds.

    rem Use "vcvars32.bat" for a 32-bit build.

    "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars64.bat"



    rem Build mpir first.

    cd C:\src\mpir-2.1.1\build.vc9



    rem Check contents of configure.bat to see allowed options. Verify that

    rem all tests pass.

    rem 64-bit binaries were built with --cpu-k8.

    configure

    make

    make check



    rem Copy the required to a convenient location for gmpy.

    rem The files are located in "lib\Win32\release" for 32-bit

    rem build.

    mkdir c:\src\lib

    mkdir c:\src\include

    xcopy /Y lib\x64\release\*.h c:\src\include\*.*

    xcopy /Y lib\x64\release\*.??b c:\src\lib\*.*



    rem Done with mpir, now build gmpy.

    cd c:\src\gmpy-1.12



    rem Convince setup.py to use the SDK tools.

    set MSSdk=1

    set DISTUTILS_USE_SDK=1



    rem Build and install gmpy.pyd

    python setup.py build_ext -DMPIR -Ic:\src\include -Lc:\src\lib install



    rem Run the test suite

    python test\gmpy_test.py



    rem (Optional) Build an installer, located in c:\src\gmpy-1.12\dist.

    python setup.py bdist_wininst
